See the dividend snowball in action. Enter your shares, price and payout to project final shares, portfolio value, total dividends reinvested, and your rising yield on cost when every dividend buys more stock.
Answer first: reinvesting dividends buys more shares, which pay more dividends, which buy still more shares — a self-feeding loop. This dividend reinvestment (DRIP) calculator models that loop year by year, growing your price and dividend over time, so you can see how a steady payout snowballs into a much larger position.
Each year: dividends received = shares × dividend per share; new shares = dividends ÷ next year's price; repeat.
Example: 100 shares at $50 paying $2.00 (4% yield), with 4% price growth and 5% dividend growth, reinvested for 10 years, grows to about 148.3 shares worth $10,973 — up from a $5,000 stake — even though you never added a cent of new money.
The magic is that reinvested dividends compound on top of price appreciation. Over decades, reinvested dividends have historically accounted for a large share of the total return of the U.S. stock market — frequently cited as roughly a third to a half of long-run returns. Turning the payout back into shares is one of the simplest, most reliable wealth-building habits an investor has.
Watch the yield on cost figure. Because a growing company raises its dividend over time, the income you earn measured against your original price climbs every year. A 4% starting yield that grows 5% annually becomes an effective 6%+ on your original cost within a decade — the reward for buying a quality payer early and holding.
This is a deterministic projection: it assumes your growth rates hold steady and ignores taxes on dividends (which can be 0%/15%/20% for qualified dividends), brokerage rounding to whole shares, and the very real possibility of dividend cuts in a downturn. Real markets are lumpy. Use it to understand the mechanics of compounding income, not to predict an exact balance.
Reality check: It assumes fixed growth rates, allows fractional shares, and ignores dividend taxes, fees and the risk of a dividend cut. Real results vary year to year. This is an educational calculator, not financial advice — verify your own numbers and see the U.S. SEC at investor.gov.

Instead of taking dividends as cash, a DRIP uses each payout to automatically buy more shares of the same stock. Those extra shares pay their own dividends, which buy even more shares — compounding your position over time.
Over long periods, reinvested dividends have historically made up a large share of total stock-market returns — often cited as roughly a third to a half. Compounding the payout, rather than spending it, is a major driver of long-run wealth.
Yield on cost is your current annual dividend divided by what you originally paid. Because quality companies raise dividends over time, this figure rises every year, so an early purchase can yield far more on your original cost than its headline yield.
Yes, in a taxable account. Reinvested dividends are still taxable income in the year received, even though you never see the cash. In tax-sheltered accounts like an IRA or 401(k), reinvestment grows tax-deferred or tax-free.
